PLOW.

Specication of Letters Patent.

Patented N ov. 1, 1910.

Application filed September 21, 1909. Serial No. 518,881.

Longview, in the county of Gregg and State4 of Texas, have invented a. new and useful Plow, of which the following is a spccication.

The invention relates to improvements inplows.

The object of the present invention is to improve the construction of plows, more especially that shown and described in Patent No. 673,606, granted to G. A. Kelly, May 7 1901, and to provide eilicient means for assisting the bolt to hold the plow point in position and to prevent a vertical or upw-ard movement of the point, when the bolt becomes loose through plowing.

A further object of the invention is to provide means adapted to interlock the landside plate or fiange of the plow point with the nose of the standard, and arranged to cooperate with the interlocking means shown in the said patent for preventing the plow points from swinging laterally toward the land when the bolt becomes loose.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriicing any of the advantages of the invention.

In the drawing Figure 1 is a perspee tive view of the lower portion of the standard, constructed in accordance with this invention. Fig. 2 is a perspective view of the co-acting plow point or share in reverse position. Flg. 3 is a transverse sectional View. Fig. 4 is a plan view.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing 10 designates the lower portion of the standard of a well known form of turning plow, and 11 designates the plow point or share. The form of these may be changed or modified as desired. The standard in the form shown is provided with the usual upright landside face 12 and the upper curved face 13, their meeting edges being indicated by 14. The plow point or share is secured upon the curved face 13 by means of a bolt 15, passing through registering perforations 16 and 17 of the plow point and the standard. Projecting from the lower portion ofthe curved face 13 and adjacent to the meeting edge 14 is an upstanding lug *18, the outer face of which forms a continuation of the upright face 12. This lug, which is thickest at its lower end, tapers gradually toward its upper end until its' upper face coincides with and merges into the upper face 13 of the standard. The lower end of the lug is also inset slightly from the lower edge of the face 13, so that the said lower edge is continuous from one end to the other.

The plow point or share 11 comprises the usual Working plate 19, having at one edge the landside plate or ange 2() and on its underside a stop rib 2l. The lower end of the standard fits snugly in the angle formed by the landside plate or ange 20 and the stop rib 21. Arranged in the underside of the plow point between the landside plate or flange 20 and the stop rib 21 and contiguous to the said landside plate or flange is a notch or recess 22, which exactly corresponds to the shape of the lug 18. One of the walls of the socket or recess 22 forms a continuation of the inner face ofthe landside flange 20. The standard is also provided at its upright landside face 12 with a lug 23, having its upper edge arranged substantially in the plane of the curved upper face 13 of the standard, as clearly illustrated in Fig. 3 of the drawing. This lng 23, like the lug 18, is thicker at its lower or front end and tapers inwardly or rearwardly until its outer face coincides with and merges into the outer upright face of the upri ht landside face 12 of the standard. The ront end of the lug 28 terminates short of the front end of the nose of the standard. The landside flange 20 is provided in its inner face with a longitudinal recess or socket 24, which corresponds exactly with the shape of the lug 23. One of 'the walls of the socket or recess 24 is arranged in the same plane and coincides with4 the lower face of the working plate 19 of the plow point.

The plow point is applied to the standard in the usual manner. The underside of the plow point bears direct-1y upon the curved als face 13 of the standard, and the landside flange fits a ainst the landside face 12. The standard wi l then fit snn ly in the angle between the landside lange'O and the stop rib 21. The openings 16 and 17 will also be in alinement, and the bolt 15 is passed through the same. The lugs 18 and 23 nt snugly in the sockets or recesses 22 and 24 and will be held therein by the bolt 15. The lug 18, as explained in the aforesaid patent, will prevent the plow point from swinging laterally toward the landside when the bolt is a little loose, and the lug 28 ofthe present invention by interlocking' with the landside flange will 'v revent a vertical or upward movement o the plow point when the bolt gets' loose from' lowing. By interlocking the plow point Wlth the standard to' prevent both vertical and horizontal or lateral 'swinging, the fastenin bolt is relieved of strain and the plow point is rigidly held in position, thereby greatly increasing the durability of the plow point and rendering the plow effective until the plow point is worn ont. Also the rigid character of the attach- Inent of the plow point greatly assists the p'l'ow in doin better work.

The face o the lug 23 inclines baclwardly with respect to the Upright landside face' 12 of the standard,- and the bottom of thel recess 2.4 inclins forwardly with respect to the' said inclined landside face 12, so that when the face of vthe lag fits against. the bottoni of the recess, the tendency will be to force the plow point in correct position against the mold aard 25,- an'd the ladside aange 20 against the landside Shoulder 26 and prevent the forward movement of the plow point. This will greatl assist the lug 23 in preventing the vrtica movement of 'the low point for the closer the plow point is 61d against the rnold board and the flange a einst the landside shoulder, the incre snug will the hl'g lit in the recess and hold the peint rigid. v

Having ths fully described iny invention, what I cla'ini as new and desire to secur'e by Letters Patent, is

1; In a plow, a standard provided in its lower or'tion at a point remote from the latidsi with a bolt opening and having its landside face provided with a lateral projection of less area than said face and avin" its front end extending in advance of the bo t opening, a share having its la-ndside' flange fitted against the landside face of the standard and provided in its face with an interioi'ly arranged socket receiving the said pa-eenen, whereby the share is' heid against ilp'v'r'rd inove'inent on the landside face', said sh having an opening registeriii' with the bolt opening of the standard, an a fastening devies passed throughthe aia apeniii In a plow, the combination of a standard having at a point remote from' the landside a vertically disposed bolt opening in its lower portion, and provided at its landside face with a tapered lug projecting laterally from said face and having its front end extending in advance of the bolt opening, and a share having a face fitted against the landside face of the standard and provided with an interiorly arranged socket corresponding in shape to and receiving said lug, whereby the share is locked against upward movement on the landside face by wedg'ing the share on the standard, said share having an opening registering with the opening of the standard, and a fastening device arranged in the' said openings and securing the share to the standard.
